How does Beet It Sport Work?
After consuming nitrate-rich beetroot juice, nitrate is absorbed into the bloodstream and taken up by the salivary glands, before being converted to nitrite by bacteria in the mouth.
Nitrite is then swallowed, absorbed into the bloodstream and transported around the body. Nitrite can be converted to nitric oxide in the blood and in various organs including muscle.
Nitric oxide is important for several processes that influence exercise performance, including vasodilation (widening of blood vessels) and muscle contractility (increase in the force of contraction).
A key effect of dietary nitrate is that it reduces the oxygen demand of exercise, meaning the muscles need less oxygen to maintain a given work rate, thereby improving exercise efficiency, fatigue resistance and exercise performance.
